ASE-25.000MHZ-C-T3 Equivalent & Substitute Parts

Part Overview

The ASE-25.000MHZ-C-T3 is a 25 MHz CMOS oscillator manufactured by Abracon LLC, designed for applications requiring a standard XO (crystal oscillator) with enable/disable functionality. This surface mount device operates at 3.3V and is housed in a compact 4-SMD, No Lead package. The part is currently active in production with RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when component availability is limited, supply chain disruptions occur, or inventory requirements necessitate alternative sourcing from qualified manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASE-25.000MHZ-C-T3 are qualified based on the following criteria:

Core Electrical Parameters (Must Match):

• Frequency: 25 MHz
• Output: CMOS
• Supply Voltage: 3.3V
• Frequency Stability: ±50ppm
• Function: Enable/Disable
• Operating Temperature: -10°C ~ 70°C

Mechanical Parameters (Must Match):

• Package Type: 4-SMD, No Lead
• Package Dimensions: 3.20mm x 2.50mm
• Mounting Type: Surface Mount

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant or equivalent
• Moisture Sensitivity Level: 1 (Unlimited)

The following parts meet all substitution criteria:

1. 7X-25.000MBB-T (TXC CORPORATION) – Direct substitute with identical electrical and mechanical specifications
2. SXO32C3A171-25.000M (Suntsu Electronics, Inc.) – Direct substitute with identical electrical and mechanical specifications

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with current manufacturing status and meet the core electrical and mechanical requirements for direct substitution. Selection between these parts should be based on the following factors:

ASE-25.000MHZ-C-T3 (Abracon LLC):

• Primary choice when Abracon supply is available
• ROHS3 compliant with documented MSL 1 rating
• Current supply: 13mA (mid-range consumption)
• Supplied in Tape & Reel packaging

7X-25.000MBB-T (TXC CORPORATION):

• Alternative when TXC supply is preferred or Abracon inventory is constrained
• RoHS compliant (meets compliance requirements)
• Current supply: 20mA (higher consumption; verify thermal budget compatibility)
• Supplied in Tape & Reel packaging
• Slightly lower maximum height (1.10mm vs 1.20mm) provides additional PCB clearance margin

SXO32C3A171-25.000M (Suntsu Electronics, Inc.):

• Alternative when Suntsu supply is available or preferred
• ROHS3 compliant
• Current supply: 10mA (lowest consumption; optimal for power-constrained applications)
• Supplied in Bulk packaging (consider reel conversion requirements for automated assembly)
• Highest inventory availability (18,245 pcs)

Frequently Asked Questions (FAQ)

Q: Can I use 7X-25.000MBB-T as a direct replacement for ASE-25.000MHZ-C-T3?

A: Yes. Both parts meet identical electrical specifications (25 MHz, CMOS output, 3.3V, ±50ppm stability, enable/disable function) and mechanical requirements (4-SMD No Lead package, 3.20mm x 2.50mm dimensions, surface mount). The 7X-25.000MBB-T has a maximum supply current of 20mA compared to 13mA for the ASE part; verify your circuit design accommodates this difference.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel packaging is pre-formatted for automated pick-and-place assembly equipment. Bulk packaging requires manual reel conversion or tape formatting before automated assembly. If your manufacturing process uses automated equipment, Tape & Reel format (ASE-25.000MHZ-C-T3 and 7X-25.000MBB-T) is recommended. Bulk format (SXO32C3A171-25.000M) may require additional handling steps.

Q: Are all three parts RoHS compliant?

A: Yes. ASE-25.000MHZ-C-T3 and SXO32C3A171-25.000M are ROHS3 compliant. 7X-25.000MBB-T is RoHS compliant. All three meet environmental compliance requirements for restricted substance use.

Q: Which part has the lowest power consumption?

A: SXO32C3A171-25.000M has the lowest maximum supply current at 10mA, compared to 13mA for ASE-25.000MHZ-C-T3 and 20mA for 7X-25.000MBB-T. For power-constrained applications, Suntsu's part is the optimal choice.

Q: Can I mix these parts in the same production batch?

A: All three parts are electrically and mechanically interchangeable and meet identical functional specifications. However, verify your quality assurance and traceability requirements, as mixing manufacturers may require separate documentation and testing protocols per your manufacturing standards.

Q: What is the moisture sensitivity level, and why does it matter?

A: Moisture Sensitivity Level (MSL) 1 indicates unlimited shelf life without moisture control requirements. ASE-25.000MHZ-C-T3 and 7X-25.000MBB-T are explicitly rated MSL 1. This classification ensures the parts can be stored and handled without special humidity-controlled packaging or baking procedures prior to reflow soldering.
